Test: Integration By Substitution - Question 1
Detailed Solution for Test: Integration By Substitution - Question 1

cos(sin-1x)/(1-x2)½……………….(1)
t = sin-1 x
dt = dx/(1-x2)½
Put the value of dt in eq(1)
= ∫cost dt
= sint + c
= sin(sin-1 x) + c
⇒ x + c

Test: Integration By Substitution - Question 2

### Integral of sin5x.cos2x is:

Detailed Solution for Test: Integration By Substitution - Question 2

So Looking at this integral, we have

Test: Integration By Substitution - Question 3

### Evaluate:

Detailed Solution for Test: Integration By Substitution - Question 3

xex = t
(xex + ex) dx = dt
= ex(x + 1) dx = dt
= ∫dt/sin2t
= ∫cosec2t dt
= -cot(xex) + c
